imc CAN-FD Interface for ARGUSfit

The CAN FD interface is a clickable module for the modular imc ARGUSfit system. Together with the analog imc ARGUSfit measurement amplifiers, several of these interfaces can be docked to an imc ARGUSfit base. The ability to acquire CAN-based measurement data and log channels can thus be flexibly added to such a measurement system.

Two CAN nodes are provided at DSUB-9 sockets with standardized pinout. For the logical decoding of the channels, the module has a local intelligence in the form of a processor. This relieves the imc ARGUSfit base unit and the overall system is easily scalable in its total performance even with several interfaces.

Highlights

• Two individually galvanically isolated CAN nodes
• CAN FD (max. 8 MBaud), CAN High Speed (max. 1 MBaud), CAN Low Speed (max. 125 KBaud)
• CAN termination can be activated by software
• Decoding of physically and numerically scaled parameters or measuring channels. Such channels can also be used as trigger source, in live analysis (OFA) and in PC-less stand-alone mode
• Logging of the raw, undecoded send and receive data as log channel in imc TSA format (Time Stamped ASCII)
• Log channel can also be decoded outside the interface via imc STUDIO BusDecoder (live) or via imc FAMOS (post-processing), thanks to embedded dbc information.
• Configurable with CAN assistant in imc STUDIO, including dbc interface (file import/export)
• Support of imc CANSAS modules (CANFX, CANFT) with configuration via dbc file exchange
• Power-via-CAN for supply of imc CANSAS modules by the imc ARGUSfit system: Can be activated by software and with electronic overload protection.
• Automated cyclic output of protocol sequences for initialization or activation of sensors and subsystems

Typical Applications

• Measurements on vehicle buses and automotive components, ECUs etc.
• Road test and test bench applications in the automotive field
• Measurements with intelligent sensors and subsystems with CAN output
• Integration of CAN-based test bench infrastructure
• In preparation: output and exchange of real-time measurement channels of the imc ARGUS system with higher-level automation and application systems, CAN-based displays, etc.

imc ARGUSfit: Flexible modular platform for fast measurement systems

Based on an imc ARGUSfit base unit, imc ARGUSfit measurement amplifier and interface modules can be combined to form complete systems by means of a robust click mechanism, which can even integrate
imc CANSASfit modules. The click connectors provide the electrical connection to the power supply and system bus.

For expansion to decentralized distributed topologies, the fast internal ARGFT system bus can be converted to fiber optic cables by means of a clickable fiber converter module.

The entire system can be controlled via a common Ethernet connection (LAN/WLAN) with a PC (imc STUDIO software) and can be networked and operated synchronously and uniformly with all other imc data acquisition instrument series. Furthermore, it can also be operated autonomously and stand-alone without PC with data storage on microSD.
